Update.

2003-03-20  Ulrich Drepper  <drepper@redhat.com>

	* include/atomic.h: Define atomic_compare_and_exchange_val_acq,
	atomic_compare_and_exchange_val_rel,
	atomic_compare_and_exchange_bool_acq, and
	atomic_compare_and_exchange_bool_rel instead of
	atomic_compare_and_exchange_acq and atomic_compare_and_exchange_rel.
	* sysdeps/i386/i486/bits/atomic.h: Define
	__arch_compare_and_exchange_val_*_acq instead of
	__arch_compare_and_exchange_*_acq.
	* sysdeps/x86_64/bits/atomic.h: Likewise.
	* sysdeps/ia64/bits/atomic.h: Define
	__arch_compare_and_exchange_bool_*_acq instead of
	__arch_compare_and_exchange_*_acq.
	* sysdeps/powerpc/bits/atomic.h: Likewise.
	* sysdeps/s390/bits/atomic.h: Likewise.
	* gmon/mcount.c: Adjust for new form of compare&exchange macros.
	* malloc/set-freeres.c: Likewise.
	* nscd/cache.c: Likewise.
	* stdlib/cxa_finalize.c: Likewise.
	* sysdeps/unix/sysv/linux/getsysstats.c: Likewise.
